+# AGENTS.md - Data Folder
+
+This folder contains source-of-truth JSON content used by the app and Toolkit.
+
+## Rules
+
+- Keep JSON valid, stable, and reviewable.
+- Add TypeScript exports and runtime validation when app code imports JSON directly.
+- Keep Toolkit placeholder files in `toolkit/` as arrays until schemas stabilize.
+- Do not put secrets, credentials, local machine paths, or private notes in this folder.
+- Prefer additive schema changes. If a shape changes, update tests and any socket/content-store validation.
+
+## Current Content
+
+- `changelog.json`: app-facing changelog entries, newest records shown first in the Change Log screen.
+- `credits.json`: Toolkit Credits source content.
+- `legal.json`: policy/legal content.
+- `toolkit/*.json`: empty array placeholders for future Toolkit authoring resources.
+
